Precautions for device overheating
If you begin to feel uncomfortable due to the device overheating, stop using the device.
When the device heats up, the features and performance may be limited or the device may
turn off to cool down. The feature is only available on supported models.
•
If the device overheats, the screen brightness, the screen refresh rate, and the
performance speed will be limited to lower the device’s temperature. Even if the battery
charging indicator icon appears, charging may be slow. When charging stops due to a rise
in the device’s temperature, the battery indicator icon will blink.
•
If the device reaches a certain temperature, a warning message will appear to prevent
device failure, skin irritation and damage, and battery leakage. Running apps will be
closed and all calling and other features will be limited, except for emergency calls, until
the device cools down.
•
If the second message appears due to a further increase of the device’s temperature, the
device will turn off. Do not use the device until the device’s temperature drops below the
specified level. If the second warning message appears during an emergency call, the call
will not be disconnected by a forced shut down.
